Last week I was routing a piece of wood with my Bosh 1600 in a router table, when unexpectedly the router quick back the piece and beginning to vibrate loud. I immediately turn it off, and checked it for damages.

Turn it on again and the vibration continues. I suppose that the spindle can be out of align due this issue.
I took the measurement and as you can see it is very misaligned.

The shaft seems to be very short and resistant, could it be bent? Or is it that the bearing has been damaged, can replacing it solve the problem?

Hard to say as is but I'd remove the bit and roll on a perfectly flat surface to see if it is obvious. You could also test using straight another bit at the shaft to see if you get the same results on the gauge and any vibration. Might indicate bit or router.

Whatever it is you'll have to take the router apart to confirm. If anything is bent then you will need a new part, you can't expect a straightened out part to work properly. I think that if you find that you need a new part you'll be out of luck finding one.

If you need parts I've had great luck with eParts. You can find them with a quick Google search.
I make a fair amount of money buying older Bosch and ELU equipment, working or not, refurbishing them and reselling them.

Can you move the spindle axially by hand?

Looks like the shaft is hard to turn, almost ratcheting. Bad bearing is my guess.

Disassemble and check if bearing is still slightly tight in its pocket. A lot of times if the bearing seizes up and spins in the pocket and the router is done for.

This weekend I start unassembly the router to check the issue.
Apparently the problem is in the bearing. As you can see in the video below, there is a small gap in the shaft.


Everything goes fine, I bought new bearing to change and back to business, but.....

IT'S IMPOSSIBLE TO RELEASE THIS COLLAR NUT. I can't properly hang the shaft to release the nut. :mad:
It's extremely locked, maybe with some thread lock adhesive. I tried almost everything, hit it with hammer, warm up the axis with a sold iron, grip pliers.... I can not release it at all.

My last resource is cutting it whit a wheel grinder, but I think it would damage the shaft thread.
Any ideais what can I do?

It almost looks pressed on. I don't think it would be threaded if it is what you grab with a spanner when loosening the collet nut.
Start looking for videos or other instructions I guess.

If you have to cut it off (hopefully an easy part to get?) then maybe drill a series of holes just through it or just shy of through it, along the line where you would cut it with a grinder wheel. With a line of weakness (and maybe another set of holes on the other side?) you should be able to pry it off without damaging the threads for the collet nut.

I can't see the threads, but when you look at the exploded view you can see a thread here:

There is also a this topic about a different issue with the collar, totally loose:
https://www.bosch-professional.com/g...748#id13287748
In the video you can also see that there is a left hand thread. He loose and tighten the collar with his fingers.

I'm now looking for 2 big nuts that fits in the collet nut to press one against other to lock the axis while trying to loose the collar with a spanner wrench.
Hope it works.

Good find, that certainly clears up the question of threaded vs. press. That looks like right hand thread to me however (granted I'm terrible with that stuff in my head, I'm one of those who has to hold it).

At least the part is cheap if you have to cut it off. I hope it doesn't come to that however. Perhaps they did try some thread locker on it since apparently there was a previous problem with them getting loose. You have to get stuff really hot to break down the thread locker, far too hot to touch, probably around 180 C. I might try that with a torch before anything else.
